2. Problematic
In recent years urban climatology hitherto focused primarily on the warming of the air. [1]. Heat flux exchanged
between the soil and urban environment play an important role through their contributions to the warming of the air.
Various authors have conducted studies on these exchanges. The synthesis of bibliographic work shows that the
authors discuss the phenomenon of exchange considering the daily net radiation is divided between the latent heat
and sensible heat [2] [3 ] [4]. To limit the warming of the air in an urban environment, the mastery of energy balance
should be a priority. Cities must anticipate this new climate data
